Free Looker Studio connectors: Google's own and partners' free plans

Free Looker Studio connectors: Google's own first

The free Looker Studio (Google now calls it Data Studio) connectors are Google's own for Google Ads, GA4 and Search Console, plus the free plans of Windsor.ai, Porter Metrics, Dataslayer and Coupler.io. Google calls Data Studio a no-cost tool. Its catalog names no Facebook Ads, LinkedIn Ads or TikTok Ads connector.

Know the limits. One Google Ads data source connects to one account you can access, or up to 50 sub-accounts of a manager account. Google says its Google Ads data sources refresh every 12 hours. The GA4 connector needs at least Read & Analyze permission on the property. With Owner's credentials, viewers see a report without their own access to the data.

The catalog also lists Google Sheets, Excel and CSV upload connectors, which suit a file you export by hand.

Free plans from partner connectors

Supermetrics and Funnel (Funnel.io) have trials and no free plan listed: Supermetrics gives 14 days and Funnel 30 days, each without a card. The free plans below cap accounts, history, refresh or rows.

Windsor.ai's answers page says a free account is never asked for a credit card. The paid step after it is Basic: $19 a month billed annually, or $23 a month on monthly billing, for 3 sources and 75 accounts, as read on October 24, 2026.

A free Facebook Ads connector for Looker Studio

Windsor.ai's free account offers every data source, Facebook Ads included, but the Forever Free plan keeps one source and one account active and reaches back 30 days. A free account starts with 30 days of 10 sources and 15 accounts before its Forever Free limits apply, and the Terms say trial access ends. The connector is in connect Facebook Ads to Looker Studio.

The other free plans cap other things: Porter Metrics at 30 days of history, Dataslayer at 1 connector, 1 user and 1 account, Coupler.io at 1 account and 100 rows a run.

The route with no connector is a CSV file from Ads Manager, added as a data source or through Google Sheets. Windsor.ai's page notes the data does not update until you export it again, and each export holds only the columns and breakdown you chose.

When a free connector stops being enough

Two sources in one report need a paid Windsor.ai plan after the first 30 days, according to Windsor.ai's Facebook Ads page. Backfills into a destination start on Basic. Free plans also set the refresh: Dataslayer allows one manual refresh a day and Coupler.io's is manual.
